PATEN .IMPROVEMENT m N'A lLlNG OR TACKINC MECHANISMS FOR BOOTS ANDSHOES.

Specification forming part of Letters Patent No. 197,212, dated November20, 1877 application filed April 30, 1877.

To all whom it may concern Be it known that I, CHARLES W. GLIDDEN, ofLynn, county of Essex, and State of Massachusetts, have invented anImprovement in Nailing or Tacking Mechanisms for Boots and Shoes, ofwhich the following is a specification: V

This invention relates to nailing or tacking mechanism for boots andshoes, and is herein delineated in connection with a hand-operatedtacking mechanism.

In this invention a pivoted feeding blade projected between adjacenttacks 'or nails at the lower end of the strip is moved laterally,takingwith it the tack or nail in the direction of the driver-passage,by means of a lever and cam, or equivalents. The upper edge of thisblade forms the lower member of the tack or nail severing mechanism, theend of the driver forming the upper member. The blade, after it is movedso as toplace atack or nail in the path of the driver, serves as oneside of the driver-passage.

Figure 1 represents, in side elevation, a hand tacking or 'nailin gmachine provided with my invention Fig. 2, an under-side view thereof,showing the blade and other parts in dotted lines; Fig. 3, anenlargedside view of part of the machine; Fig. 4, a cross section of thestrip-guide; and Fig. 5, a detail of the blade, holder, and slide-bar.

The head a of the machine, to be grasped and held by the operator, haswithin it a bar, b, and driver 0, the bar being surrounded, as usual, bya spiral spring to lift it. The foot d at the lower end of the head isroughened to engage the stock, and above its lower end is attached, byscrews 2, the strip-guide e, provided with a suitable channel or way toreceive the strip, a spring, 3, holding the latter down therein. Theguide shown is shaped to .reeeive a T-shaped strip.

The bar I) is provided with a cam shaped projection, f,extendedlaterally through a slot in the head a, which, as the driverdescends, strikes a roller, g, at the upper end of a lever, h, pivotedati on abracket, j. The lower end of this lever his connectedwith ablade-holder, k, to which is pivoted, at l, a blade, m. This blade, atits forward end, enters between lugs opposite a slot in a slide, 1%,adapted to be moved at right angles to the movement of the holder k, bymeans of a lever, 0, pivoted at p, and actuated in one direction by acam, r, at the lower end of lever h, and in the other direction by aspring, 8. The spring t moves the lever h in opposition to the camprojectionf.

A shoulder on the blade-holder k strikes and moves forward a lockingdevice,u, it being adapted to enter a slot in the slide a, so as to holdit and the blade firmly in position when a tack is being driven.

Assuming that the lever h, blade-holder k, and blade m are in thepositions shown in Figs. 2 and ,3, then, as the driver-bar is depressedits projection f actuates the lever h, moving forward the blade-holderin the direction of the arrow, Fig. 2, the blade m, A

hinged to the holder, passing through the slot in the slide a, andbetween the two tacks at the lower end of the strip. In this conditionthe lever o is moved by the cam r, to actuate the slide a in thedirection of arrow 3.

The slide carries with it the blade, and the latter, resting between thetacks at the end of the strip, moves the strip until the tack nearestthe driver is placed in line with it, when the locking device u, movedforward by the bladeholder k, enters an opening in the slide n, andholds it and the blade in position, while the driver completes itsdescent, severs the headforming portion of the strip transverselybetween its lower end and the upper edge of the blade, and drives thetack. The blade, held in locked position, serves as one wall of thedriver passage as the tack or nail is driven.

I claim 1. The combination, with the strip-guide and foot, provided witha driver-passage, of a reciprocating blade adapted to be entered betweenadjacent tacks or nails, and to be moved laterally to place a tack to bedriven in line with the driver-passage, and close one side of suchpassage, substantially as described. v

2. The reciprocating blade-holder and its pivoted blade, in combinationwith the head and slide, and mechanism to move the slide In testimonywhereof I have signed my name to this specification in thepresence oftwo subscribing witnesses.
